This is about the laptop PC of my wife, who is not aware that anything out of the ordinary had occured in the past. There has been a big and time consuming update of Windows 10 a few weeks agio, but we learned that this occured with other people as well and the PC had performed afterwards quite okay for some time.
Lenovo ideapad 100-15IBY
purchased about 6 months ago
no extra hardware installed
Windows 10 home edition
automatic updates activated
virus protection by Windows Defender
Malwarebytes Anti-Malware (Premium version) installed
The PC is used mainly to communicate via facebook, organise, manipulate and display photos, do some office work (OpenOffice)
Startup and login is fine, maybe a little longer than before, but this may well be a misconception.
Then the response to any input gets pretty slow. Starting any app takes minutes. Occasionally there seems to be no response to mouse clicks at all. Especially when responding to some system generated prompts. You have to click a dozen times to close the box. This deterioration of performance occured overnight, however this PC has never been very fast in responding to input.
What I tried:
We did not create a 'Microsoft account' for my wife does not use any app where you would need such an account. Since the last update Cortana was running after startup, so we disabled it, that is, set all the options in Cortana's controls to 'no' or 'off'.
I did remove some faulty software that came with the PC as recommended by the manufacturer lenovo.
I tried to identify resource consuming services using Task Manager, but could not identify such an item.
I ran a scan with Malwarebytes but no hazards were identified.
I started the PC while disconnected to the internet (by disabling the router) with the same result.
Any advice and help would be appreciated.
